The purpose of the work is to investigate the existence and the possibility of recovering economically interesting elements, such as precious metals and rare earth elements, from phosphor layers of cathode ray tube wastes. Therefore, a series of analyses took place in the precipitation material that resulted from the disassembling and wet processing of the cathode-ray tube screens. An applied recycling method, that mechanically with water enriches precipitates of cathode ray tube glass (wet cathode ray tube recycling method), is hosted in a small-medium recycling company. Identification of the amorphous and crystalline phases in combination with the micro-structural characterization and the chemical, major, and trace-element analysis were performed in waste materials as well as in the precipitate that resulted from the wet cathode-ray tube recycling process. Important quantities of zirconium, yttrium, lanthanum, cerium, and gold appear in the precipitate. Conclusively, a hydraulic classification enrichment method should be, furthermore, examined.

这项工作的目的是研究从阴极射线管废料的荧光粉层中回收经济上有意义的元素（例如贵金属和稀土元素）的存在和可能性。因此，对由于阴极射线管屏幕的拆卸和湿法处理而产生的沉淀物质进行了一系列分析。小型机械回收公司采用了一种实用的回收方法，该方法用水机械地富集阴极射线管玻璃的沉淀物（湿阴极射线管回收方法）。结合非晶组织特征和化学，主要，对废料以及湿阴极射线管回收过程中产生的沉淀物进行了痕量和痕量元素分析。沉淀物中会出现大量的锆，钇，镧，铈和金。最后，应进一步研究水力分级富集方法。
